Description

Technical Field

[0001] The utility model relates to the field of metal ore sales equipment, in particular to a display cabinet for metal ore sales. Background Art

[0002] Metal ore refers to ore containing metal components. According to the types of metals contained, it can be divided into ferrous metal ores, such as iron, manganese, chromium, etc.; non-ferrous metal ores, such as copper, lead, zinc, aluminum, tin, molybdenum, nickel, antimony, tungsten, etc.; precious metal ores, such as gold, silver, platinum, etc.; rare metal ores, such as niobium, tantalum, beryllium, etc. Single metal ores contain only one metal component, and polymetallic ores contain more than two metal components. In the sales process of metal ores, it is usually necessary to extract some samples and place them in display cabinets for buyers to view. At present, metal ore display cabinets are divided into fixed display and rotating display. Fixed display cabinets cannot easily view the shape of the ore around. Multiple booths of rotating display cabinets need to be equipped with multiple sets of drive components to control their rotation. The equipment cost is high and it is not convenient to promote and use. Utility Model Content

[0025] A vertically extending regular polygonal strip-shaped transmission block 602 is fixed to the top of the transmission rod 6, and a transmission groove capable of engaging the transmission block 602 to transmit and connect the transmission rod 6 is vertically arranged at the center of the bottom end of the vertical shaft 3. When ore is placed in the tray 2 above the vertical shaft 3 to press down the vertical shaft 3, the transmission groove at the bottom end of the vertical shaft 3 is engaged with the outer side of the transmission block 602 at the top end of the transmission rod 6 to transmit and connect the vertical shaft 3 and the transmission rod 6.

[0026] As an optional embodiment, a turntable 301 is coaxially arranged on the outer side of the vertical axis 3 above the partition 9, and the turntable 301 and the vertical axis 3 are rotatably matched through a thrust bearing. A spring 302 is sleeved on the outer side of the vertical axis 3 below the turntable 301, and the compression stroke of the spring 302 is greater than the distance between the vertical axis 3 and the transmission block 602. The bottom end of the transmission rod 6 extends downward to the bottom of the top cabinet 1, and a top hole 101 for accommodating the vertical axis 3 is vertically penetrated at the top of the top cabinet 1. The vertical axis 3 and the top hole 101 are clearance-matched, and a bottom hole 102 for accommodating the transmission rod 6 is vertically penetrated at the bottom of the top cabinet 1. A thrust bearing supporting the rotation of the transmission rod 6 is arranged inside the bottom hole 102, a gear 601 is fixed at the bottom end of the transmission rod 6, a plurality of gear rings 802 are arranged on the outer side of the synchronization rod 8 corresponding to the transmission rod 6, the gear rings 802 are meshed with the gear 601, and a motor 801 as a rotation power component of the synchronization rod 8 is arranged at the outer end of the synchronization rod 8, the motor 801 is fixed on the outer side of the base 7, ensuring that the motor 801 can drive the synchronization rod 8 to rotate, and the gear ring 802 fixed on the outer side of the synchronization rod 8 is used to drive the plurality of gears 601 and the transmission rod 6 to rotate synchronously;

[0027] A plurality of groups of clamping tubes 5 are arranged around the outer circumference of the tray 2, and a circular airbag ring 4 is sleeved on the outer side of the vertical axis 3 below the tray 2. A support ring that rotates and cooperates with the top side of the top cabinet 1 is arranged at the bottom of the airbag ring 4. The support ring and the vertical axis 3 are clearance-matched to ensure that the airbag ring 4 can still rotate with the tray 2 and the vertical axis 3 when the tray 2 moves downward and is compressed. A plurality of groups of fixing ears 201 that support the clamping tube 5 are arranged around the outer circumference of the tray 2, and a bellows 501 is arranged at the outer end of the clamping tube 5. The bellows 501 is made of a hose material, and the outer end of the bellows 501 is downwardly connected to the airbag ring 4.

[0028] The top side of the airbag ring 4 is bonded and fixed to the bottom side of the tray 2, and the airbag ring 4 is a non-elastic plastic sealing structure, which ensures that when the airbag ring 4 is compressed, the gas can be introduced into the clamping tube 5 through the bellows 501. The clamping tube 5 is radially penetrated by a push rod 502 at one end away from the bellows 501 along the tray 2. The push rod 502 extends into one end of the clamping tube 5 and is fixed with a piston disk 504. The piston disk 504 is slidably sealed with the inner wall of the clamping tube 5, and an arc-shaped clamping plate 503 is fixed to the outer end of the push rod 502.

[0029] With the above structure, when the ore is not placed on the top side of the tray 2, the spring 302 pushes the turntable 301 to keep the bottom end of the vertical shaft 3 and the transmission block 602 at the top of the transmission rod 6 in a separated state. At this time, the motor 801 drives the synchronous rod 8 to rotate, and the gear ring 802 on the synchronous rod 8 engages with the upper gear 601 to drive multiple groups of transmission rods 6 in a synchronous rotation state. Since the transmission rod 6 and the vertical shaft 3 are in a separated state, it is ensured that when no ore is placed on the tray 2, the group of trays 2 is in a stationary state; after the ore is placed on the tray 2, the tray 2 is subjected to the downward pressure of the ore and moves downward. At this time, the vertical shaft 3 moves downward using the turntable. The disk 301 compresses the spring 302, and at the same time, the transmission groove at the bottom end of the vertical shaft 3 is clamped to the outside of the transmission block 602 to connect the transmission rod 6 with the vertical shaft 3, so as to ensure that the vertical shaft 3 drives the tray 2 to rotate and display the ore in rotation; when the ore is placed on the tray 2 and the tray 2 is moved down and compressed, the downward movement of the tray 2 compresses the airbag ring 4, and the air in the airbag ring 4 is input into the clamping cylinder 5 along the bellows 501. The continuously increasing air pressure in the clamping cylinder 5 pushes the piston disk 504 and the push rod 502 to move, so that the clamping plate 503 at the outer end of the push rod 502 is used to support and clamp the ore prevented in the middle of the push disk;

[0030] The trays 2 of multiple groups of booths are connected by transmission through the lower vertical shaft 3 and the transmission rod 6, and the multiple groups of transmission rods 6 are connected by synchronous transmission through a synchronization rod 8. In addition, the transmission state of the vertical shaft 3 and the transmission rod 6 is associated with whether the ore is placed, so as to ensure that the trays 2 of the booths without ore are in a static state, which is convenient for the trays 2 to be in a static state during the subsequent placement of the ore, and at the same time does not affect the rotation display state of the ore in other booths. After the ore is placed, it can automatically clamp and start to rotate, which is more convenient. In addition, the multiple groups of booths are driven by a group of motors, and the display actions do not affect each other. The equipment cost is low and it is convenient to promote and use.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
